Hi,

How to find a STL class size, for example: string. I would like to
know what the size of the implementation of this class, I am not
interested in the size of its object but the class itself. There are
discussion regarding addition of all the data member of the class/
structure to find out its size, but is there a neat way to find out
class' size?

A class does not have a size since it does not exist anywhere than in
your source code. The only way to measure the size of a class would
be to count the number of characters or lines of code that is used
in its definition.

I am sorry not stating my question clearly. My intention is to find
out how many memory is consumed by a class definition. What kind of OS
tool will give me such information?

A class definition exists only in C++ source. Once the program is
created from the source, there is no such thing as "class definition".
Perhaps it's time you acquaint yourself with the way compilers work.
It would require knowing how computers work, as well. "Inside the
C++ Object Model" by Lippman is a good book to start with.
